Abstract
A spring screw comprises a bolt and a compression spring. The bolt comprises a cylinder body, a nut and a screw portion, wherein the nut and the screw portion are respectively formed at two ends of the cylinder body. One end, close to the screw portion, of the cylinder body is provided with an annular fastening groove, and a washer is arranged in the annular fastening groove. The compression spring is sleeved on the cylinder body, and one end of the compression spring is abutted on the washer. The cylinder body is provided with a connecting portion connected with the annular fastening groove. The diameter of the connecting portion is gradually increased from the annular fastening groove to the nut direction. The tail end of the compression spring can be avoided from being blocked in the fastening groove, so that yield of assembly products can be improved.
Description
Technical field
The present invention relates to a kind of fixed block combination, especially refer to a kind of Spring screws.
Background technique
When carrying out the element assembling, Spring screws is the assembly of commonly using.Fig. 1 and shown in Figure 2 be a kind of Spring screws, this Spring screws comprises that a bolt 10 and is set in the Compress Spring 20 on this bolt 10.The screwed screwing part 13 that this bolt 10 comprises a cylindrical body 11, is formed on the nut 12 of cylindrical body 11 1 ends and is formed on cylindrical body 11 the other ends.Offer formation one annular slot 11a near screwing part 13 places on this cylindrical body 11, be used for arranging an O type packing ring 30 in this annular slot 11a.This Compress Spring 20 is set on the cylindrical body 11, and the one end is connected on the nut 12, and the other end is connected on the O type packing ring 30.In use, the housing that is screwed togather element can be offered formation one through hole, the diameter of this through hole greater than the diameter of bolt 10 less than the diameter of O type packing ring 30, the bolt 10 of this Spring screws is passed this through hole be screwed on the inside that is screwed togather element, and O type packing ring 30 gears of this Spring screws are connected on the housing around the through hole simultaneously.This Compress Spring 20 provides elastic force for bolt 10, O type packing ring 30 can be attached to more closely be screwed togather on the element, prevents that Spring screws from owing to concussion gets loose, increasing the reliability that screws togather.Above-mentioned Spring screws following problem can occur when assembling: Compress Spring 20 ends are stuck among the annular slot 11a easily, thereby cause Spring screws to move up and down, and elastic force can not be provided, and then can't be normally sealed.
Summary of the invention
In view of this, be necessary to provide a kind of Compress Spring of avoiding to be stuck in Spring screws in the annular slot.
A kind of Spring screws, it comprises a bolt and a Compress Spring.This bolt comprises a cylinder and is respectively formed at nut and the screwing part at these cylinder two ends.Described damaged surface is offered near an end of screwing part and is formed an annular slot, is provided with a packing ring in the annular slot.This Compress Spring is set on the cylinder, on this packing ring of one end butt.Have a joint that is connected with annular slot on the described cylinder, the diameter of this joint on along annular slot to the nut direction increases gradually.
Above-mentioned Spring screws is because bolt has the joint that is connected with annular slot, and the diameter of this joint is to increase gradually to the nut direction from annular slot, therefore can avoid the end of Compress Spring to be stuck in the annular slot, stablize the quality of assembling processing procedure, improved the yield of completed knocked down products.

Following embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See also Fig. 3, Spring screws of the present invention comprises that a bolt 100, is arranged on O type packing ring 200 and on the bolt 100 and is set in Compress Spring 300 on this bolt 100.
See also Fig. 4, described bolt 100 comprises a cylinder 110, be formed on the nut 120 of cylinder 110 1 ends and the screwing part 130 that is extended by the other end of cylinder 110.The diameter of nut 120 is greater than the diameter of cylinder 110.In the present embodiment, it is one round table-like that nut 120 is, and rotatable this nut 120 of assembler is threaded into Spring screws in the assembled element.The diameter of screwing part 130 is less than the diameter of cylinder 110.In the present embodiment, it is one cylindric that screwing part 130 is, and the surface is formed with screw thread.
Described cylinder 110 surfaces are offered near an end of screwing part 130 and are formed an annular slot 111, and this annular slot 111 is used for arranging and gear connects O type packing ring 200.This annular slot 111 is an annular bottom wall 112 near screwing part 130 1 sides, and in the side of annular slot 111 near nut 120, this cylinder 110 has an a junction 113 that is connected with annular slot 111.This annular slot 111 is made of jointly this annular bottom wall 112 and this joint 113.The diameter of this joint 113 increases to nut 120 directions gradually from annular slot 111, makes this joint 113 times narrow wide, is a cone table shape.Cylinder 110 surfaces outwards also are convexly equipped with near nut 120 places and form an annular abutting part 114.
Being understandable that joint 113 is not limited to the cone table shape in the present embodiment, also can be other level and smooth arc surface round table-like.
See also Fig. 5, described O type packing ring 200 is set in the annular slot 111, and it can be connected on the annular bottom wall 112 of annular slot 111.
Described Compress Spring 300 is set on the cylinder 110 of bolt 100, and an end of Compress Spring 300 is connected on the annular abutting part 114 of cylinder 110, the other end then is connected on the O type packing ring 200, and O type packing ring 200 then is connected on the annular bottom wall 112 of annular slot 111 by the elastic force of Compress Spring 300.This Compress Spring 300 is used for providing elastic force to bolt 100, O type packing ring 200 can be attached to more closely be screwed togather on the element, prevents that Spring screws from getting loose, and increases the reliability that screws togather.
In use, the housing that is screwed togather element can be offered formation one through hole, and the diameter of this through hole greater than the diameter of bolt 100 less than the diameter of O type packing ring 200, the bolt 100 of this Spring screws is passed this through hole be screwed on the inside that is screwed togather element, 30 on the O type packing ring of this Spring screws is connected on the housing around the through hole by gear by the elastic force of Compress Spring 300 simultaneously.Owing to have an a junction 113 that is connected with annular slot 111 on the bolt 100 of Spring screws, and the diameter of this joint 113 increases to nut 120 directions gradually from annular slot 111, thereby so that the end of Compress Spring 300 can freely move up and down in annular slot 111, and can not be stuck in the annular slot 111.
Compared to prior art, Spring screws of the present invention is because bolt has the joint that is connected with annular slot, and the diameter of this joint is to increase gradually to the nut direction from annular slot, therefore can avoid the end of Compress Spring to be stuck in the annular slot, stablize the quality of assembling processing procedure, improved the yield of completed knocked down products.
Be understandable that, for the person of ordinary skill of the art, can make change and the distortion that other various pictures are answered by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
